Okay I just figured out what happened here. Sorry for my misunderstanding in the other comment thread, I fell into the same trap initially.

@Lemmy users - OP is a Mastodon user, so when OP responded to the comment with an @ and attached image, Lemmy federation didn't pick up the attachment. I know we have images in attachments natively, so I don't know if this is an upstream bug in Lemmy / Mastodon or some interaction between lemmy.world and Mastodon.scot.

@twoowls73@mastodon.scot - you may not have realized that your Mastodon post generated a Lemmy thread. Welcome to another corner of the Fediverse if you're new to Lemmy. Some of the animosity in the comments here probably came from the fact that we can't see the image you attached to from our interface. Right now the comment is sitting at 36 net down votes, probably because our corner of the Fediverse didn't have the full context
